Hi!
Firstly judging by the situation I totally understand the difficulty you are facing right now!
Next Steps
I have some follow up questions please answer them :
Which teeth are to be extracted and which are to undergo RCT. Your dentist mist have mentioned tooth numbers or teeth on your prescription. Share them.
Health Tips
If the RCT and extraction teeth have clashing quadrants by any chance, you should go for RCT first, followed by extractions.
Because, post extraction swelling and sensitivity is normal.
